Postoperative renal artery stump leak

Pseudoaneurysm formation is an uncommon complication of simultaneous aortic and renal artery revascularization procedures that has been noted to occur primarily at sites of anastomosis. We present the computed tomographic and angiographic findings of an unusual case of contained leak arising from the proximal renal artery stump with associated inferior vena caval compression and thrombosis in a patient who had had abdominal aortic aneurysmectomy and bilateral aortorenal bypass.
